Answer: Avocados, with few exceptions, are generally thought to be self-fertile. One is usually all you need. You didn't include your zip code so I'm not sure of your gardening region, but following are the most often grown avocados in home gardens:
Anaheim: A highly productive tree. Heavy bearer of tasty, green, 18-32oz. fruit. Smaller sized tree is an excellent choice for backyard use. Tree is frost-tender, making it a better choice for coastal or milder climates. Self-fertile.
Bacon: A popular variety for all avocado climates. Medium-sized, green-skinned fruit has flavorful, smooth and creamy flesh. Medium-sized, attractive, upright tree is very cold hardy. Self-fertile.
Fuerte: The second largest commercially produced avocado variety. Smooth, green-skinned fruit has excellent-flavored, creamy flesh. Large, spreading tree has an average hardiness rating. Alternate bearer produces more regularly in inland areas. Self-fertile.
Hass: The most popular avocado variety for commercial and backyard use. Fruit has green, 'pebbly' skin which turns black when allowed to ripen off of the tree. Flavorful flesh is prized for its high oil content and 'buttery nut' flavor. Attractive tree is a consistent producer. Self-fertile.
Jim Bacon: A seedling of Bacon that is slightly more frost-resistant than Bacon. Medium-sized, green-skinned fruit has a flavorful, smooth and creamy flesh. Heavy-producing, attractive, upright tree is self-fertile.
Little Cado TM# 50552: The only true dwarf avocado variety. A consistent bearer of good quality, green-skinned fruit. An excellent choice for backyard use, as a container specimen, or as an espalier. Best for use in milder climates or if protected from winter frosts. Self-fertile.
Mexicola: An excellent quality, frost-hardy variety. Mexican-type fruit reaches 4-8oz, with thin, black skin. Bears heavily both inland and along the coast. Compact tree is perfect for backyard use.
Stuart: An excellent choice for colder climates. Compact, spreading tree bears small, black-skinned, Mexicola-type fruit. A great choice for backyard use. Very cold-hardy tree is self-fertile.
Best wishes with your landscape!
